Rust中的函数调用

注意区别语句和表达式哟。

Rust是一门基于表示式的语言，牢记！！！

fn main() { println!("Hello world!"); another_function(5, 6); let y = { let x = 3; x + 1 }; println!("The value of y is: {}", y); let x = plus_one(5); println!("The value of x is: {}", x); } fn another_function(x: i32, y: i32) { println!("The value of x is: {}", x); println!("The value of y is: {}", y); } fn plus_one(x: i32) -> i32 { x + 1 }
